Interview Questions

  • Q1. Where do we us transformer
  • Q2. Do we use transformer in our homes
  • Q3. What is the o/p voltage of mobile charger.Can u calculate the rating of transformer used in Mobile charger.calculate it taking o/p voltage as 3.5 V?
  • Q4. What is SCR n what protection we use for SCR?
  • Q5. How 3-phase magnetic field is produced and also derive taht its magnitude is constant?
  • Q6. How do we control frequency and voltage ?
  • Q7. What is ferranti effect
  • Q8. What happen to Generator and Motor during ferranti effect and also to transmission line?
  • Q9. What is armature reaction and interpole winding.why we use interpole winding?
  • Q10. What is the benefits of armature reaction?
  • Q11. How torque is produced in all type of M/c.{DC,Synch,Induc} ?
  • Q12. Principle of operation of induction m/c?
  • Q13. Slip and speed characteristic of Induction M/c?
  • Q14. What are classification of DC M/c ? 15. speed torque characteristic of all type of DC M/c ?
  • Q15. Importance of Power angle?
  • Q16. How we can reduce harmonics? (all type of winding done to reduce harmonic)
  • Q17. A ckt was given (was a chopper ckt).and said that if we give the o/p of this ckt to a transformer,what will be the o/p waveform?
  • Q18. What is hysteresis and eddy current loss ? ld is made sinusoidal in cylindrical and salient pole m/c? 26. Draw 3-phase AC waveform. 27. Which motor r we using i...read more
  • Q19. What are the condition to be satisfied for production of torque in any m/c
  • Q20. What is two field revolving theory?
  • Q21. What is the reason of production of torque in synchronous M/c?
  • Q22. Basic of stability of M/c and why for transient stability load angle can go beyond 90 degree?
  • Q23. Basic of stability of M/c and why for transient stability load angle can go beyond 90 degree? 33. prove W=1/2*c*v^2 .
  • Q24. 1-2 basic n/w ckt. with inductor and capacitor.they also used tank ckt.they made some changes and ask for change in current in a particular branch

Interview Preparation Tips

Round: Test
Experience: Dear Juniors, I would like to share my feelings and interview experience so that u may be benefited from this. Gate 2013 turned to be so easy, so that anyone can easily get rank around 500 without any preparation. But Inspite of studying at made easy I get 1207 Rank. I was so depressed that I cant express in words. I was able to score under 50 rank but the result was very bad. BARC OCES/DGFS 2013 Program: Gate cut off was gate score 574 around 1400 rank and I was called for Interview.

Round: Technical Interview
Experience: Beside these some conditional and practical questions were there.I don't remember all the questions. around 45-50 questions was asked to me in 1 hr 40 min interview and i answered almost 45 of them. 2-3 question they give me hint.. They asked me to wait outside. After 2 min they called me and give the white slip and said that u have a very high probability of selection. I more thing I want to say that getting white slip doesn't ensure ur selection bcz in 2013 almost 200-250 student get the slip and only 10 are selected at BARC Mumbai. overall selection including IGCAR, RRCAT, NFC, VECC, BRIT and all through OCES 2013 program is 56 in electrical engineering.
Tips: I hope this will help u in future...wish u all d best ...!!!!
